The new 2.3L is just to improve emissions and I guess performance if they wanted to. IIRC the original 2.3L didn't have port injection on it like the larger Ecoboosts, which is the major difference.
As for a hybrid variant, that may or may not come-if the Rumored Affordable Truck EV is roughly the size of a Ranger, Ford might want to use that as a stick to make people buy it vs a PHEV Ranger.
